WIRE-FRAME MACHINE- Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed March 28, 1905. Serial No. 252.546.

To (all whom it may concern:

Be i t known that I, ABRAHAM VELLEHAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved lVire- Frame Machine, of which the following is a full, clear, and exact description.

' The purpose of my invention is to improve upon the construction of the wireframe machine for which application for patent was made December 13, 1904, Serial No. 236,887, the improvement being principally to so construct and mount the frame-supporting arms that their inner ends may be set relatively to a given center and their outer ends adapted as required to any point in a circular circuit and whereby the arms may be adj usted independently in a lateral or rotary direction as may be required by the conditions of the work.

A further purpose of the invention is to provide a very simple machine of the type described and one wherein the parts may be readily and quickly adjusted to adapt the machine for the formation of any style of wire-frame hat, regular or irregular in general contour, and also to provide a centering device having means for adjustment, en abling the de 'ice being placed in position to accurately center the crown of any wireframe hat, and, furthermore, to so construct the machine that it can be adapted to any shape of crown and so that after a shape has been completed it can be readily and quickly freed from the machine without danger of injuring the shape.

The invention consists in the novel construction and combination of the several parts, will be hereinafter fully set forth,

and pointed out in the'claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding-parts in all the figures.

Figure 1 is a plan view of the machine. Fig. 2 is a sectional plan view taken substantially on the line 2 2 of Fig. 3. Fig. 3 is a vertical section taken substantially on the line 3 3 of Fig. 1. Fig. 4. is a horizontal section taken practically on the line 4. 4 of Fig. 3. Fig. 5 is a horizontal section through the base, taken substantially on the line 5 5 of Fig. 6. Fig. 6 is a vertical section through the base, taken substantially on the line 6 6 of Fig. 5. Fig. 7 is a perspective view of the head-section of the centering element. 8 is a perspective view of one of the shoes adapted to have rocking support in the base and in which the standards of the supporting-arms are adjustably secured. Fig. 9 is a side elevation of one of the upper members of one of the supporting arms, parts being broken away and some of the clamps for the framing members carried thereby being in section. Fig. 10 is a transverse section through the upper member of the supporting arm shown in Fig. 9, a section through a clamp carried thereby, and a side elevation of a ortion of the framing member held by the clamp. Fig. 11 is a perspective view of a portion of a modified form of an upper or carrying member for a supporting-arm and a clamp adapted thereto, and Fig. 12 is a transverse section through the carrying member shown in Fig. 11 and its clamp.

The base A is preferably made in sections, as is illustrated in Figs. 3 and 6, comprising primarily a hollow bottom section a and a table-section (11 The hollow bottom section consists of a body 10, containing a chamber 10 open at its lower portion, and a tubular standard 11, which is attached to or constitutes an integral portion of the top of the body, the standard being in communication with the chamber 10 and a flange 11 ad aptedto rest upon any desired support. The table-section a consists of a'disk body 12 and a tubular hub 13, which extends downward from the body at its center. The hub 13 is enlarged where it connects with the disk body 12 of the table to provide a chamber'14 open at the top, which chamber is of greater diameter than the bore of the hub be low it, and at the upper marginal portion of this chamber the upper face of the body 12 is beveled from a point about centrally bety een its inner and outer edge portions downward to said chamber 1 1, as is illustrated at 15 in Figs. 3 and 4. The body 12 of the table, as is particularly shown in Fig. 4, is provided with a series of radial slots 16, extending from its outer edge some distance into the beveled portion 15 of the body, and at the under face of said disk body 12 of the table, at the inner end portions of the slots, ears 17 are formed, (shown by dotted lines in said Fig. 4,) which ears are pierced for the passage of bolts 18. Preferably the bodymember 12 of the tablesection is provided with eight slots 16, as illustrated, but this number may be increased or decreased, as desired.

nating at its upper end in a head having a horizontal slot therein, and a set-screw 23 is made to enter the said slot.

Below the head of the spindle 20 and at the upper portion of the spring 19 two horizontal flanges 24 and 25 are integral with or are attached'to the spindle, a space being made to intervene between the said flanges, as is clearly shown in Fig. 3. The flanges 24 and 25 are preferably made of such size that they may pass down Within the spring 19 should occasion require. The upper portion of the spindle 20 in its normal position is 'so held by the spring 19 but the spindle is adapted to be drawn downward to release the framing members from the hat-frame at any time, as will be hereinafter particularly described. WVhen the downward movement of the spindle 20 is made, the spring 19 is compressed and the downward movement of the spindle and its release or upward movement to normal position is effected as follows: A circumferential slot 26 is provided in the side of the body 10 of the bottom section (1, adjacent to the flange l1, and the said slot has a low section 26, which is quite close to the flange 11*, a high section 26 and an inclined intermediate sec tion connecting the high and the low sections, as is best shown in Fig. 6. On the uper wall of the chamber 10 in the bottom of the body member 10 a cam projection 27 is formed at the said slot 26, the under or working face of which cam projection 27 conforms to the shape of the upper wall of the said slot, being even therewith, as is shown in Figs. 5 and 6. The said cam projection 27 consists of a high member 27 at the lower section of the slot 26, a shallower member 27 at the high section of the slot,-and an intermediate inclined connecting member. Immediately opposite the said cam projection 27 a second and corresponding cam projection 28 is formed upon the upper wall of the chamber 10*, as is best shown in Fig. 5, and the positions of the members are just opposite to the positions of the members of the cam projection 27, as the shallower member 28 of the cam projection 28 is opposite the higher or deeper member 27 of the camprojection 27, the shallower member 27 of the cam projection 27 being opposite the deeper or higher member 28 of the cam projection 28, and

base A the j their connecting inclined sections therefore incline in opposite directions.

A lever 29 is passed into the chamber 10 through the slot 26, being loosely connected with the lower end of the spindle 20 by the nuts 21 and 22, as is shown in Fig. 3, and, as is illustrated in Figs. 3 and 5, the said lever terminates in a foot 30, adapted to engage with the working face of the cam projection 28, while the body portion of the lever is in en gagement with the working face of the cam projection 27. Thus when the lever 29 is carried to an engagement with the shallower sections of both cam projections 27 and 28 it will be at the higher end of the slot 26 and the spindle 20 can be carried to this higher position by the spring 19. When the lever 29 engages with the intermediate inclined mem bers of the said cam projections, the spindle 20 will naturally be drawn down to a certain extent; but when the lever 29 engages with the deeper or higher members of the cam projections 27 and 28 the spindle 20 will be drawn down to the limit of its movement in that direction.

In order that the shifting lever 29 may be held in its adjusted position, rack-teeth 31 are formed upon the flange 11 of the bottom member a in front of the slot 26, and a thumblatch 32 is pivoted upon the lever 29 to engage with the said rack, as is shown in Fig. 3. When the hub member 13 of the base is in position on the tubular standard 11, the hub is prevented from being withdrawn and is yet free to turn on the tubular standard 13 by introducing a screw 33 into the hub and into an annular groove 33 eXteriorly formed in the said tubular standard.

Although the flanges 24 and 25 are shown of slightly less diameter than the diameter of the spring 19, the same or of greater diameter, if desired.

The body or bed member 12 of the tablesection a carries shoes B, (shown particularly in Fig. 8,) and each shoe is adapted to carry a supporting-arm C, detachable therefrom and capable of radial and lateral adjustment upon the shoe. The shoes B correspond in number to the number of slots 16 in the bed or body plate 12 of the table-section a and are of segmental shape, so that when all of the shoes are in position upon the said body or bed plate 12 they practically cover said body or bedplate, as is shown in Figs, 1 and 2. Each shoe B is independent of the others, yet all are given simultaneous rocking motion on the bed or body plate 12 when the spindle 20 is moved up and down. Each shoe at a point about centrally between its inner and outer end is provided with a downwardly-extending lug 34, and these lugs are passed down through the slots 16of the said body or bed plate 12 to a position between opposing ears 17, and the shoes are hinged to or are pivotsaid flanges may be of the ally connected with the bed or body plate 12 by passing the bolts 18 heretofore referred to through the said ears and lugs, as is shown in Figs. 3 and 4.

it will be observed, especially by reference to Fig. 3, that the shoes have rocking movement on the body or bed plate 12 of the tablesection a by reason of the beveled or inclined surface on the top of the plate beneath the inner portions of the shoes, enabling their inner ends to be depressed and their outer ends elevated when desired; but normally the shoes rest in a horizontal position.

The rocking movement mentioned is imparted to the shoes by the vertical movement of the spindle 20 and is brought about by forming a toe 34 at the inner or contracted end of each shoe and introducing the toes into the space between the flanges 24 and 25 on the spindle 20, and the toe of one shoe is provided with a slot therein, as is shown in Fig. 8, for a purpose to be hereinafter explained.

Each shoe B is provided with a yoke 36, transversely located upon its upper face, open at the front and at the rear, and each yoke is provided with a segmental slot 37 in its upper portion, and in the same portion of each yoke a series of segmentally-arranged apertures 38 are produced. The supportingarms C, one of which'is used in connection with each shoe B, are preferably inwardly curved at their inner ends and are straight or vertical at their outer ends when in position for use, and each supporting-arm terminates at its lower end in a horizontal foot 39 or a foot extending inward at an angle to the body of the arm. The feet of the supporting-arms C are adapted to enter the yokes 36 of the shoes B and are of such shape that they may be turned in the said yokes, as on a pivot, or adjusted in direction of the sides of the machine as may be required Without changing their relation to the center of the machine.

The upper and lower faces of the feet 39 are flat, and the preferred general contour is substantially triangular, as is shown best in Fig. 2. Each foot is provided with a clamping-screw 40, which in practice is passed through the segmental slot 37 of a yoke 36 and into the foot, the screw being preferably provided with a square head. This arrange ment enables each individual supporting-arm to have independent pivotal and lateral adjustment and provides means for securing the arm in its adjusted position; but in order that each arm shall be firmly secured after adjustment a set-screw 41 is provided for each series of apertures 38, which setscrew after the adjustment of a supporting-arm is screwed into one ofthe apertures 38 to a firm engagement with the inner end portion of the foot of the arm, as no matter how a supporting-arm C is adjusted in a shoe B the inner end of the foot 39 of the arm will be beneath one or the of a series 38 in the illustrated in Fig. 2.

The supporting-arms constitute a basket, and, as stated, any one is independently adjustable and any one or more can be removed when not needed. Each su )portingarm is provided with an inwardly-extending carrier member D at its upper end, either integral therewith or attached thereto. The carrier members D may be either in the form of slotted bars, as isshown in Figs. 1, 3, or 9, or may be solid, as illustrated at D in Figs. 11 and 12.

In the drawings the carrier members D are shown screwed to the supporting-arms C, and in Figs. 1, 3, and 9 each member D is provided with a slot 42, extending longitudinally from top to bottom, and a second slot 43, which extends longitudinally through from side to side, so that the said members D for the supporting-arms C are of skeleton construction.

Each carrier member D is provided with any desired number of removable and adjustable clamps E. Each of these clamps consists of a block 44, mounted to slide in a side slot 43 of a carrier member, being provided with a threaded post at one side and an elongated aperture 46, extending through from top to bottom, the end walls of which apertures are preferably convexed, as is shown at the right in Fig. 9.

When a block 44 is placed in position in a carrier member D, one side of the block is flush with one side of the carrier and the threaded post 45 extends beyond the other side of the carrier, while the aperture 46 in the block is longitudinally located with respect to the carrier. Finally, a thumb-nut 47 is placed on the threaded post 45.

The clamps E are prevented from leaving the carrier members D by passing the body portions 48 offraming members F through the vertical slots 42 of the carriers and through the elongated slots 46 of the clamping-blocks 44, as is shown in Figs. 1, 3, 9, and 10. After a clamp has been adjusted in the carrier and a framing member F has been adjusted in the clamp the parts are held in adjusted position by tightening up the. thumb-nut 47, as is shown in Fig. 10, which nut by exerting pressure on one side of the carrier D causes the framing member passed through the body-block of the clamp to be firmly wedged between the opposing longitudinal walls of the vertical slots 42 of the carrier at the point where that especial clamp is located, but will not interfere with the separate adjustment of other clamps on the same carrier member.

The body portions 48 of the framing members F may be straight throughout or their upper portions 49 may be curved or given other of the apertures yoke of the shoes, as is any desired angle or inclination with reference to the main body portion as may be required in the formation of a hat-frame, as is shown in Fig. 3; but each framing member terminates in a hook-head 50.

In the construction of a framing member F a round wire of suitable gage is usually employed, reduced at its upper end, so that the hook-heads of the framing members are materially of less diameter than their remaining portions, and the upper portion of the body is made to gradually taper where the reduction is made. The hook-heads 50 are substantially of 3 formation, the intermediate and lower members being brought close together; but the intermediate and upper members are sufiiciently wide apart to freely receive the wire employed in making a hat-frame. Under this construction of the heads 50 it will be observed that no sharp points are presented to cut the framing-wire, and that the wire is really guided to the upper or receiving sections of the hook-heads.

In the further construction of the machine I employ a centering device G for the crown of the hat-frame, which device is removable from the machine and is constructed for lateral and vertical adjustment, so that it may be adapted to any form of crown or any location of crown with respect to the brim of the hat. This centering device consists of a base 9 and a body-section g. The base g comprises two arallel horizontally-spaced members 51 and 52, located one above the other, the members being connected at one end, and the lower member 52 is introduced into the slot heretofore mentioned, located in the head of the spindle 20, and is adjustably and removably held therein by the set-screw'23, carried by the spindle 20, as is shown in Fig. 3. The body-section g of the device comprises a lower tubular member 53, preferably enlarged at its lower end and provided at said end with a slot to receive the upper member 51 of the base-section g, being laterally adjustable upon said member, and the said tubular member 53 is heldin adjusted position by a set-screw 54, carried thereby and which engages the aforesaid upper member 51 of the base-section.

A rod member 55 is telescopically placed in the tubular member 53, so as to obtain the vertical adjustment of the said'centering device, and the rod member 55 is held in adjusted position by means of a set-screw 56, which set-screw is located at the upper portion of the tubular member 53 and engages with the rod member 55, as is also shown in Fig. 3.

At the upper end of the rod member 55 a head 57 is located, and in the upper face of this head, which is preferably flat and of disk-like formation, a series of intersecting slots 58 is produced, the slots being usually eight in number. These slots receive and hold the central portion of the cross-wires which constitute the top of the crown of a hat and effectually hold the said wires in position, perfectly centered, while the other portion of the hat-frame is being constructed.

I desire it to be understood that any preferred means may be employed for capping the head 57 to prevent the wires from rising therefrom after they have been placed in position.

It will be observed that each particular clamp may be adjusted independently of its support and that each of the framing members employed in the actual formation of a hat-frame can be independently adjusted; also, that any desired number of framing members may be permitted to remain in their clamps and the clamps loosened to permit such framing members as are not needed to be dropped down out of the way and yet be at hand for immediate service.

A frame of any desired shape is first constructed by hand. The lever 29 of the machine is placed in its normal position, (shown in Fig. 3,) whereupon the spring 19 causes all of the supporting-arms to take their normal positions, also shown in Fig. 3, and the centering device is adjusted to take the eight top wires H where the cross and is then secured in its adjusted position. Next the supporting-arms C are shifted or pivots or are given both adjustments to bring their carrier members in proper relation to the center of the crown or the direction in which the eight main crown-wires H may be led with reference to the circular wires H of the crown and brim. After the adjustment of the supporting-arms C they are secured in position in the manner stated. The various framing members F are now adjusted in their clamps, and the clamps are adjusted in their carrier members D to outline the circular wires H of the frame at points where the main crown-wires H are to be secured thereto. After the proper out swung upon their line hasbeen obtained all the clamps are firmly tightened up and the model is removed by carrying the lever 29 in a direction to draw the spindle 20 downward, and con sequently all the carrier members and upper portions of the supporting-arms C inward. The lever 29 is then returned to its normal position. The operator now proceeds to lay the main cross-wires H for the new frame in the slots 58 of the head of the centering device G and passes other wires around the various horizontal rows of hook-heads 50, thus producing the necessary circular wires H, each of which wires is suitably secured its ends. Finally, the main crown wires H are carried in their proper alinement across the circular wires. H, connecting them, and are secured to them in any approved manner.

In directing and manipulating the main shoes and as is shown in Fig. 3. After the crown-wires II the operator does not change his position relative to the machine, but simply turns the body of the machine upon its bottom base member a until the desired point in the frame to be operated upon can be conveniently reached. In so turning the machine it is absolutely necessary that the position of the centering device G shall not change from its adjusted position relative to the supporting-arms C, and consequently all parts of the body of the machine must move together. Therefore the spindle 20 is compelled to turn with the table-section a and the shoes B, and this is done by passing a pin 59 down through the upper flange 24 of the spindle 20 into the slot 35, heretofore referred to as produced in the inner end of one of the frame is completed the lever 29 is moved in a direction to draw the spindle 20 downward and the carrier members D inward, which releases the frame just completed from the hook-heads 50 of the framing members, and the hat-frame will spring from the machine-of its own accord.

In order to render it absolutely certain that none of the carrying-arms C shall move inward through any possible downward movement of the spindle 20 after the carrying-arms have been set to their normal position when the lever 29 is in position to hold the said arms 0 in their normal position, the foot 30 of the said lever is held between the cam projection with which it engages and a lug 60, secured to an inner side wall of the bottom chamber 10.

It will be observed that by reason of the numerous adjustments for the supportingarms C shown and described their carrier members at their inner ends may be set relatively to a given center and their outer ends adapted as required to any point in a circular circuit, enabling the framing members to be set to bring about the production of any shape, whether regular or exceedingly odd and irregular, both with respect to the crown and the brim portion of the hat.

In Figs. 11 and 12 I have illustrated the preferred form of carrier D for the sup porting member C in which the said member is a solid bar, rectangular in cross-section, and the clamps E for this bar are made in two members 0 and e. Each clamp member 6 and 6 adjacent to one end is provided with a rectangular recess 61 in its'inner face, so that when the two members are brought together the two recesses being one opposite the other produce a rectangular opening in which the carrier-b ar D is more or less snugly accommodated, and at the opposite end of the two members a and e transverse spacingribs 61 are formed to maintain the members in proper alinement when in position on the carrier-bar, as they do not meet over the bar at their opposite ends, and in the further con- 1 struction of themembers e and e alining apertures 62 are made in them between the recesses 61 and the spacing-ribs 61. When the members 6 and e are in position on a carrier bar or member D, a screw E is passed through them, having ahead 63 atone end, the opposite end being reduced and threaded, and the said screw E is provided with an aperture 64, partly in its head and partly in its neck, which aperture 64 is sufliciently large to permit the passage of the body of a framing member F. After the members of the clamp are in position on the carrier-bar D and the screw E is in position in the said members a thumb or other form of nut 65 is loosely screwed upon the threaded portion of the screw E and then the body portion of a framing member is passed through the aperture 64, whereupon by tightening up the thumb-nut 65 the clamp is firmly held on the carrier-bar D and the framing member F is also firmly held in the clamp. The head of the screw is made flat and smooth with rounded edges, so as not to interfere with the passage of the wire to the hook-heads 50 of the framing members F. This form of clamp can be made to extend up or down from the carrier-bar D and be equally effective in either position. It is evident that the clamp is readily adjustable on the carrier-bar and that the framing member can be quickly and conveniently adjusted in the clamp.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
